15° 56' S., 33° 55' E. — *' Pursuing our course for two days 

 through an uninteresting country, covered with tropical 

 vegetation, we crossed the Shikambe and Mbjora rivers, 

 both of which give their waters to the Zambesi above 



J- • Lupata gorge, and pitched a camp at a place which I have 



.. i .'-designated the Palm Wells, 800 feet above the sea. . . . 

 Every now and then the Tsetse would alight upon 

 our thinly-clad bodies, making us jump again as though 

 twitched with the fine lash of a whip "(Vol. II., pp. 



■'• ' 64-65). 



'- Tsetse-iffy **^^^ ^^^ southern base of tJie Kapirizange 



Mountains: 1884. Approximate geographical position, 

 fi-om the author's map, 15° 49' S., 34° 5' E.— " Just before 



-' ■ beginning the ascent of the Kapirizange range, I had seen 



' Tsetse-fly ; but in the mountains none were to be found " 



(Vol. II., p. 75). 



Donkeys, though " more tenacious of life than horses 

 or oxen when in the fly country," eventually " pine away 

 and die like other victims" (Vol. II., pp. 118-119). 



Tsetse-fly not seen in the vicinity of Livingstonia, at the 



southern end of Lake Nyasa : 1884. — "No Tsetse-fly was 



• seen here, but it is more than probable that the deadly 



insect is as migratory in its habits as the game on whose 



dung it breeds "* (Vol. II., p. 193). 



[In the map at the end of Vol. II. — " Map showing 

 route from the Cape of Good Hope across the Zambesi 

 River at Tette to Lake Nyassa in 1884. From the 

 Survey by W. Montagu Kerr, C.E. Scale of English 

 •miles — 1 inch = 38 miles " — the occurrence of the Tsetse- 

 fly in different regions is shown in red. A dotted curved 

 line running from about 19° 10' S. lat., and the 29th 



<•■ parallel East longitude to about 17° 50' S., 30° 35' E., is 



marked " Approximate Southern Limit of Tsetse-Fly." 

 The " Southern Limit of Tsetse-Fly," south of the Zam- 



■■' • besi, is again shown by a line running east and west 

 from about 16° 20' S., 31° 8' E. to 16° 20' S., 32° 20' E. ; 

 the country between this line and the Zambesi is marked 



'^ - •' Tsetse-Fly Belt." North of the Zambesi a line running 

 W.N.W. — E.S.E., across the northern extremity of the 

 Salumbidwa Mountains, from about 15° 45' S., 33° 40' E., 



* [Captain J. F. Elton found Tsetse abundant at Livingstonia in 

 August 1877.^0/. 59.]
